Honda RA271E and 272E

Hi all,
I am doing researches about the engines used on the Honda F1 cars during the 1964 and 1965 seasons and asking for some help.
Being more specific I would like to know something more about their oil and water systems and fuel metering unit, does anyone know anything about it?
I know aRA271E engine is on display at the London Design Museum so if someone ever managed to take some picture to it could please share? It would be very interesting to see an image about its front side, to see what was fixed on the sump (Oil filter? Starter motor?).
Many thanks in advance to you all.
Best,
Gab
